It; will be understood that the various cyl*- inders, shafts and rollers heretofore, and -to berhereinafter, referred to, extend from side fra-me to side frame of the macliine,Y and:

that the various parts'supporting-and actuating same are duplicated'adjacentv said side,

1 frames.

nthe accom aan ino' drawings thesdater attachment is located adiacent and below-the l l J n feedfshelf ofthe machine, (not. shown) which location is a matter of convenience since it 1 permits accessibility7 to the mechanism for the purpose of setting theadjustable vrtype members and cleaning same, aswell as the adjustment ofthe attachment for vtheproper locating of theiiinprint taere'from, in'relation tothe imprint or transferreddesign fromthe cylinder j This attachment comprises a shaft 19 mounted at'each end in a bearing link 2.0

pivoted uponthe main frame `of the machine below the feed shelf.

Y or dimensions. Acting upon each link is a spring'rodv lmeans lof which an ordinary dater head 24 may be securedto the Wheel.

rlhis dater. headneed Snot be vdescribed in A detail Vsince it is of the usual and well known construction common in what is known as hand; dating machines, and consistsmere'ly of Aa frame having a plurality of wheels therein bearing different monthsof the year, digits by which the days of the month may .beindicate'd andjdiiferent years. The latter,

if desired, may be .dispensed with' since the year-- is no'. great factor' as tothe printing of sheets', the completion of whichV will occur in Y days..rv Year indicia, however,.inay be used if desired. f

The shaft 19 is rotated from the gearA 25 of the cylinder 10,1through the gear-Qfcarried by said shaft. The ratio of thejwheel 22 to the cylinder 10, and ofthe Vgear 26 to Ythe gear 25 is as 1 to 4, since thev cylinder 104 is aV double blanketed cylinder capable of @making two impressions withieach revolution thereof andthe blankets are so s xaced.

. a P apart'asto permit this ratio. 'Ivhe'propor-v y tions-of the wheelmust be such-that the .types Y carried thereby will reach the-printing position only once duringV Vthe transfer of theA ink designupon the; blanketll, and will `be accuratelytimed with relation tothefcylin der' 1G/so' as to always makethe imprint at a. predetermined"point of the blanket' or both blankets, in the event `of the use of Ytwo blankets; upon said cylinder.

Also` carried byV and `rotatable with the shaft 19 is a bearing disk 27'V adapted toen-v l gage anY end bearing disk 28 ofthe cylinder cumferentially or axially 4of the shaft19 to permit the proper timing of the transferfofl the ink design from the date-r head tol the blanket 11, or to properlyfposition said wheel-Y in relation to the transferred ink designu'pon the blanketso as to secure a desired position` Y ing of the imprint upon the printed sheet.

yBothrofthese adjustments are to compensate for'necessaryvariancerin the place of the imprint' due toiinprints of different sizes Considerable nicety in both adjustmentsrinay be required, although ordinarily thereis suiiicientmargin allowed on the printed sheets, to aiford ample space for the date limprint in a positonwhere, .with the trimming ofi thefsheets, it Will be removed. from-any ofthe complete imprints.

When -the i wheel 22 is moved axially of the shaf-t 19 itis also necessary to move the arm y311 axially vof the rod 35 lso as to secure a proper co-oper ating relation between the inking roller 33 v.a'r'l'dthe dater' head upon said wheel 22.2 It is'falso; necessary tomove' the a-rmslO and 13 with the` arm 34. Since theA vibrator roll 16 is primarily provided to coact With the inking' roller 14;, axial adjustment of this lvibratorrollV` is impossible.

lt` is customary, however, in a printing pressf'of the type inconnection Witliwhich the invention isl illustrated, tol use a number of Vnarrow vibratorrolls positioned at spaced distances along the shaft carrying the roll 16 so that the' inking roller33 may be positioned within the operative range of any of these vibrator sections; Y Y' Ofcourse-'itis possible, with some classes of work, 'to' use a continuous vibrator roll, and when such is the case, norestrictions are placed-upon the extent of axial adjustment of the wheel 2Q and the parts cooperating therewith- Y When the wheel, the inking rollerand other coeoperating parts have been properly adjusted in relation to the/cylinder 10 and to the vibrator roll, Vthe linksv 20 may be adjusted so as to ensure the proper engagement of the vwheels of the dater head1 24 with the blanket 11, and the arm 34 maybe restored to its normal position asshown in Fig. 1, where itwill pick up ink from a vibratorroll16 and transfer it tothe dater wheels. Y

If there is not a proper inkingfop'eration by the roller either'l as a result of animproper enga-gement thereof with the'vibrator roll or with the dater lhead,the roller 33 may be adjusted in relation to the arm 34 and roll lby means ofthe adjusting'screws 38 and 41. By moving the screwel toward or from' the arm 10, the roller 33 will be moved in an upward or downward are from or toward the vibrator; roll 16 and the wheel 22; By means ofthe screw 38, theroller 33 may be' moved substantially horizontally towa-rdor from said rollarnd said wheel. By the alternate useof said screws 38 and 41', the roller 33 may be universally adjusted so as to accurately engage both the roll 16 andV the dater head Wheels.V Y i Y f When the foregoing adj ustmentszhave been marde, power may be applied to the machine, and with each rotation ofthe wheel 22 the dater head wheels will be inked and the charactors thereon rwill be transferred in ink to the blanket 11 at a pointV where an impression will be made in the desired marginal position u onthe printed sheet. blankets upon the cylinder 10, the date will 'betransferred toeach of these blankets inthe same position;- With aratio of 1 to l betweenthe gear 25an`d tliegear 26 the two blankets upon the cylinder will be diametri*-v cally opposite veach other and will/,be spaced-v lof the wheels 2N2', the dater wheels reaching the *printing position, during one revolution' of the wheels QQbetW'een the blankets. The roll 16,*in addition to vcuttinginkup'on-the A.roller 14, fwill transfer ink toY thefroller 33 which will apply itto the dater wheels.

While the amount of ink used will be very small, this is of little or lnoimportance as the quality of ,thef impression madeby the dater head is limited merelyV to legibilityl' Where Wide sheets are to be printed, Vit i's possible to use any ,desired number of `wheelsA 22 so that the date impression will appear' upon each sheetl inthe' event of thecutting of large sheets into'smafller ones preparatoryV to their run-upon another machine. 'lhje possibility of adjustment of the Ywhee`lsr22 so as to cause the'imprintto be upon either the forward, rear or'side margins will permit the cutting of the sheet both longitudinally and transversely and still have each portion bear the date of the imprint lof the background tint. 1 y 'i The dater head wheels are set by hand and their position is not changed during the run of the press. i

In machines of the typetowhich my invention relates, ink applied bythe rollers 14 may bein isolated or adjo'ini'ngstripes`r and of differentcolors,in which case the vibrator roll ordinarily will be made upV ofv spaced sec-v tions as heretofore referred to, oronly one color be used throughout the length ofthe' saidrollers 14s, in which case a continuous vibrator 4roll -may be'used. In the rst instance, by locating the wheel 22 with relation to a sectio'nof the vibrator roll having a particular color upon one press and locating ,it upon another press so as' to have it inked in another color, it is possible to Videntify the press upon'which the sheets rwere printed by the colorof the imprint.

The construction and location of the dater mechanism is such as to .permit substantially the same degree of accessibility `to the plano-` graphic offset cylinder asjthough'the press Vwere notV equipped therewith. The location ofthe attachment, however, i's not material to the invention considered in its broader There being two' ilo iis
